Achtung Panzer: Kharkov 1943 is a single player, second world war, turn-based strategy game. An extremely well researched military command operation, that gives you the God-like ability to command and view your troops based on actual archival material, even to the point of eye witness reports and on the field testimonials, incredible to say the least. The battle of Kharkov was a series of operations on the Eastern front back in 1943, involving the German Army and the Red Army. Needless to say, it wasn't one of history's finest endeavours. I won't get into the history of the battle here, if you want to know more, wiki it, it makes a very sobering read.
